Use and test case to come shortly.

Semantics of parameters named Index and Idx were inconsistent between
"include/llvm/IR/Attributes.h", "lib/IR/AttributeImpl.h" and
"lib/IR/Attributes.cpp": sometimes these were fixed 1-based indexes of IR
parameters (or AttributeSet::ReturnIndex for IR return values or
AttributeSet::FunctionIndex for IR functions), other times they were the
internal slot for storage in the underlying AttributeSetImpl. I renamed usage of
the former to "Index" and usage of the latter to "Slot" ("Slot" was already
being used consistently for the latter in a subset of cases)

1. Verify::VerifyParameterAttrs in "lib/IR/Verifier.cpp" and
AttrBuilder::removeFunctionOnlyAttrs in "lib/IR/Attributes.cpp" (only called
by Verify::VerifyFunctionAttrs) separately maintained a list of function-only
attribute types. I've consolidated the logic into a new function used for
both cases in "lib/IR/Verifier.cpp", so this logic is in one place (other
than the AsmParser front-end)
2. Various functions in "lib/IR/Verifier.cpp" passed AttributeSet around by
reference needlessly, as it's just a handle to an immutable pimpl body.

It's sometimes beneficial to emit a testcase with the old style attribute
syntax. Allow someone to do this.

* We only ever specialize these templates with an instantiation of ELFType,
so we don't need a template template.
* Replace LLVM_ELF_COMMA with just passing the individual parameters to the
macro. This requires a second macro for when we only have ELFT, but that
is still a small win.

I will remove the isBigEndianHost function once I update clang.
The ifdef logic is designed to
* not use configure/cmake to avoid breaking -arch i686 -arch ppc.
* default to little endian
* be as small as possible
It looks like sys/endian.h is the preferred header on most modern BSD systems,
but it is better to change this in a followup patch as machine/endian.h is
available on FreeBSD, OpenBSD, NetBSD and OS X.

This is a rework of the broken parts in r179373 which were subsequently reverted in r179374 due to incompatibility with C++98 compilers. This version should be ok under C++98.

The register allocator expects minimal physreg live ranges. Schedule
physreg copies accordingly. This is slightly tricky when they occur in
the middle of the scheduling region. For now, this is handled by
rescheduling the copy when its associated instruction is
scheduled. Eventually we may instead bundle them, but only if we can
preserve the bundles as parallel copies during regalloc.

MIPS64EL relocation entries have up to three relocation operations. Because
libObject only exposes a single relocation name, use the concatenation of
the individual relocation type names.

Original message:
Print more information about relocations.
With this patch llvm-readobj now prints if a relocation is pcrel, its length,
if it is extern and if it is scattered.
It also refactors the code a bit to use bit fields instead of shifts and
masks all over the place.

This will be used in clang to decide if it should create an @file or not. It
will be tested on the clang side.

It was returning the loaded address of the section containing the relocation,
which really doesn't seem to be the intent of this function.

Add support for the COFF relocation types IMAGE_REL_I386_DIR32NB and
IMAGE_REL_AMD64_ADDR32NB for 32- and 64-bit respectively. These are
similar to normal 4-byte relocations except that they do not include
the base address of the image.
Image-relative relocations are used for debug information (32-bit) and
SEH unwind tables (64-bit).
A new MCSymbolRef variant called 'VK_COFF_IMGREL32' is introduced to
specify such relocations. For AT&T assembly, this variant can be accessed
using the symbol suffix '@imgrel'.

Compact unwind has an encoding for when we're not able to generate compact
unwind and must generate an EH frame instead. Track that, but still emit that CU
encoding.
